Abstract (en)
A teletext receiver has a television signal input circuit (2, 3) for receiving a television signal including teletext data signals, a teletext signal processor (12) for decoding the teletext data signals and obtaining teletext data, a teletext memory (14) for storing teletext data, the teletext signal processor (12) generating teletext picture according to the teletext data, and a display (10) for displaying the teletext picture. The teletext signal processor (12) reads out the teletext data from the teletext memory (14) at double of the speed for displaying the teletext picture on the full size of screen and the display (10) displays the teletext picture at half size on one half of the screen thereof. The teletext signal processor (12) decodes teletext data for two pages and the display (10) displays teletext pictures of the two pages on the screen. The teletext signal processor (12) decodes teletext data for one or more pages with numbers included in one of the two pages displayed on a half area of the screen of the display. If one of the two pages includes one or more page numbers, and if any one of page numbers is selected, the teletext picture of the selected page is displayed on the other half of the screen. The teletext receiver may further comprise a picture in picture processor (11) for generating a video signal representing a video picture in smaller size than half of the screen size, and the display (10) displays the video picture in the small size on the other half of the screen. <IMAGE> <IMAGE> <IMAGE> <IMAGE>
